NAME

       libpfm_intel_bdx_unc_imc  - support for Intel Broadwell Server Integrated Memory Controller (IMC)  uncore
       PMU

SYNOPSIS

       #include <perfmon/pfmlib.h>

       PMU name: bdx_unc_imc[0-7]
       PMU desc: Intel Broadwell Server IMC uncore PMU

DESCRIPTION

       The library supports the Intel Broadwell Server Integrated Memory Controller (IMC) uncore PMU.  This  PMU
       model only exists on various Broadwell server models (79, 86).

MODIFIERS

       The following modifiers are supported on Intel Broadwell server IMC uncore PMU:

       e      Enable edge detection, i.e., count only when there is a state transition from no occurrence of the
              event to at least one occurrence. This modifier must be combined with  a  threshold  modifier  (t)
              with a value greater or equal to one.  This is a boolean modifier.

       t      Set the threshold value. When set to a non-zero value, the counter counts the number of IMC cycles
              in which the number of occurrences of the event is greater or equal to the threshold.  This is  an
              integer  modifier with values in the range [0:255].  i Invert the meaning of the threshold or edge
              filter. If set, the event counts when  strictly  less  than  N  occurrences  occur  per  cycle  if
              threshold  is  set to N. When invert is set, then threshold must be set to non-zero value. If set,
              the event counts when the event transitions from occurring to not occurring  (falling  edge)  when
              edge detection is set. This is a boolean modifier
